| 摘 要： | 提出了一种新的自适应分层多播拥塞控制方案(ALM)。ALM是发送方与接收方共同驱动、由路由器辅助流量控制的拥塞控制方案,通过把发送方的动态分层和接收方的自适应速率调整有机结合,不仅增强了分层多播的适应能力,提高了系统的吞吐量,而且较好地满足了TCP友好性。仿真实验表明,ALM能有效地利用网络带宽,解决网络带宽的异构性问题,并能通过接收端计算TCP友好速率,使接收端达到与TCP流公平竞争网络资源的目的。

| Abstract: | A new adaptive layered multicast congestion scheme,ALM is proposed.ALM is a joint sender-receiver driven and router-assisted congestion control scheme.By combining the dynamic layering technique at sender and the adaptive rate control at receiver,ALM not only improves the adaptiveness and throughput,but also satisfies TCP-friendliness.The simulation results show ALM strategy can use network bandwidth effectively,and it also solves the p roblem of network bandwidth heterogeneity. Besides,it can calculate the... |
